Abstract

Japanese quails were divergently selected for antibody titer to inactivated Newcastle disease virus vaccine. Correlated responses of body weight at different ages, egg weight and egg number (first 45 days), fertility and hatchability percentages, some serum parameters and phagocytic activity were also estimated.
Actual selection differential values from the base to the first, from the first to the second, from the second to third and from the base to the third generations were 2.54, 1.96, 1.4 and 5.9, respectively, in the high line and-2.4, - 2.47, -1.35 and-6.22, respectively in the low line. The average response per generation was 0.88 and - 0.93 in the high and low lines, respectively. Cumulative correlated response was 0.21 and-0.09 g in both high and low lines. The correlated response of egg number and egg weight during the first 45 days of egg production and hatchability percentage was small and insignificant in both selected lines. Differences in phagocytic activity or phagocytic index among lines were insignificant. Serum from quails of the high line was significantly (P<0.01) higher in total serum protein  (4.61±0.47 g/100ml), globulin (2.80±0.47 g/100 ml) and gamma globulin (0.51±0.02 g/100 ml) than the low line (total protein, 3.05±0.38; globulin, 1.52±0.38; gamma globulin, 0.44±0.02).
